Popular Abstract in Swedish Dieselmotorn, uppkallad efter sin uppfinnare Rudolf Diesel, patenterades 1892 och har sedan dess bidragit väsentligt till utvecklingen av samhället. Den viktigaste användningen är som kraftkälla i fordon och detta användningsområde ökar fortfarande. Andelen dieselmotorer i nyregistrerade personbilar i Västeuropa har nyligen passerat 50 %. För kommersiella fordon som lasThis project deals with questions related to generic diesel combustion research and optically accessible engines are used to study the combustion process. Images of the combustion are analyzed together with in-cylinder pressure and exhaust gas emission measurements. The results can be divided into two main categories: one about evaluations of optically accessible engines and one about studies of e

President Barak Obama's high-profile summit with the heads of Middle East Arab states in Camp David in May 2015 did not yield satisfactory results, not only because America's global strategic priorities have changed, but also because there are deep-seated contradictions in the US regional security commitments given the importance of maintaining Israel's military superiority.

Popular Abstract in Swedish Biogas, som i huvudsak består av metan och koldioxid produceras när mikroorganismer bryter ned organiskt material utan tillgång till syre, så kallad rötning. I princip kan alla typer av organiskt material användas för att producera biogas men vanligast är till exempel avloppsslam, olika typer av avfall från hushåll och industrier, gödsel, grödor och odlingsrester. BiogAddressing today’s challenges of reducing our dependence on fossil fuels and related emissions of greenhouse gases requires measures such as increased energy efficiency and replacement of fossil energy carriers with renewable ones. Biogas is one of the fastest growing renewable energy sources in the world and the overarching purpose of the research presented in this doctoral thesis is to explore t

This paper presents the concept and initial work on a microfluidic platform for bead-based analysis of biological sample. The core technology in this project is ultrasonic manipulation and trapping of particle in array configurations by means of acoustic forces. The platform is ultimately aimed for parallel multistep bioassays performed on biochemically activated microbeads (or particles) using su

Using accurate correlated wave functions calculated earlier by Bunge and by Larsson, we have constructed the Hohenberg-Kohn-Sham density functionals and exchange-correlation (ground-state) potentials and have obtained orbital energy eigenvalues for a number of light atoms by in principle exact numerical algorithms. While the uppermost occupied density-functional eigenvalue always gives an exact ex

This paper uses the framework of ecofeminism in its exploration of two rural modernist novels, Sylvia Townsend Warner’s Lolly Willowes (1926) and Mary Webb’s Precious Bane (1924). The development of ecocriticism and ecofeminism in the 1980s saw a proliferation of work on the relation between literature, gender and the natural environment (Glotfelty and Fromm, 1996; Gaard, 1993; Warren, 1997).
